Rewatched the Oregon game and he left 15 completions on the field due to errant throws.
He also isn't seeing the field under pressure. There was one particular play where the TE went 10 yards down the middle and turned around in the zone. Sefo stepped up under some pressure and doesn't see him, but throws to a RB who is molested. TE had nobody around him and is in the middle of the field. That's got to be the #1 thing you look for when you are stepping up inside.

If it's the same vs. ASU, it's time to baptize the next guy up. It just is.
